Summary
Facelet Tag name: <ui:include>
Facelet Tag class: org.apache.myfaces.view.facelets.tag.ui.IncludeHandler
The include tag can point at any Facelet which might use the composition tag,
component tag, or simply be straight XHTML/XML. It should be noted that the
src path does allow relative path names, but they will always be resolved
against the original Facelet requested.
The include tag can be used in conjunction with multiple <ui:param/>
tags to pass EL expressions/values to the target page.
